Question

Language = JAVA

Create a new Java file called PhotoBillingYourLastName with a public static void main.

Create three overloaded computePhotoBill() methods for Shutterfly.

When computePhotoBill() receives a single double parameter, it represents the price of one photo book ordered. Add 6% tax and return the total due as a double.

When computePhotoBill() received two parameters, they represent the price of a photo book and the quantity ordered (int). Multiply the two values, add 6% tax and return the total due.

Finally, when computePhotoBill() receives three parameters, they represents the price of a photo book, the quantity ordered, and a coupon value. Multiple the quantity and price for a new subtotal, compute the coupon discount by multiplying the coupon value by subtotal, the reduce the subtotal by the calculated coupon value. Finally, add 6% tax and return the total due.

In the main method, call each method testing to make sure you receive the correct values and back. For example, with these calls (using printf to two decimals), I would receive the following:

computePhotoBill(19.99); // 21.19

computePhotoBill(19.99, 2); // 42.38

computePhotoBill (19.22, 2, .1); // 36.67

       System.out.println(df.format(obj.computePhotoBill(19.99, 2)));
       System.out.println(df.format(obj.computePhotoBill (19.22, 2, .1)));
      
      
   }
}
